Doubt in Threading

[Rahul Siddharth]

Hi Folks.I have a simple doubt in threading.From the threading chapter I see that "Only methods can be synchronized".Later in the chapter I saw "Synchronized" being used on Objects and blocks of code.Doesnt that mean Synchronized can be used on Reference variables(object) as well?

Thanks.

when you synchronize a method or block you are actually obtaining a lock on that object..

Doesnt that mean Synchronized can be used on Reference variables(object) as well?

what actually book meant was you cannot write like::
private synchronized int a = 6;
private synchronized String s = "JavaRanch" ;

you can only use the synchronized kryword either with a method or a block...
